IPC: B21B1/46
Filed: 1986-10-07
Abstract: PURPOSE:To reduce the manufacturing cost of a thin steel strip by setting a draft and a rolling temp. at a 1st pass of a direct finishing rolling based on requirements shown by a prescribed equation.

Title: Oil feed device
Inventor: YOYASU MITSUHARU
IPC: B67D7/32
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and load on a pump by controlling a pump motor so that a high/low number of its revolution is obtained, in an oil feed device. SOLUTION: In a step 2, whether or not an oil feed nozzle is detached from a nozzle hook is judged. In the case where it is detached, a pump motor is rotated at a low speed in a step 3, the presence or absence of a flow pulse from a flow meter is judged in a step 5, and when liquid-oil discharge is detected, the motor is driven at a high rotating speed in a step 6. After oil is actually fed with the oil feed nozzle, the motor is driven at a low rotating speed in a step 9. Thus, the number of the revolutions of the pump motor can be controlled according to the operation of feeding the oil, power consumption and load applied on the motor when oil feed is not carried out can be reduced, and the life of the motor can be extended.

Title: Integrated circuit having thyristor circuit
Inventor: TAKAHASHI HIROAKI
IPC: H03K17/16
Filed: 1983-12-16
Abstract: PURPOSE:To make normal gate driving of a thyristor possible even if a surge current is flowed in, by connecting the collector and the emitter of an NPN transistor TR and a resistance between the P gate and the cathode of the thyristor and connecting the emitter of an NPN TR2 to the collector of the NPN TR. CONSTITUTION:In case of driving of an SCR, a driving current is flowed in the course passing a diode D1, the base and the emitter of a TR1, the P gate of the SCR, and the earth by a driving circuit to turn on the SCR. If a surge current is flowed in during driving of the SCR, the surge current is flowed in the course passing a capacitor C, the collector and the emitter of the TR2, P gate of the SCR, and the earth. The TR1 is not turned on during driving of the SCR because the forward voltage of a level shifting diode D2 is higher than the voltage between the collector and the emitter of the TR1. Since the TR1 is turned off during driving of the SCR, the driving current is not flowed in the course passing the collector and the emitter of the TR1 and the earth.
